Brand: Frigidaire

the refrigerator side stays at the set temperature, but the freezer side doesn’t go lower then 41 degrees I have the setting at 5 degrees.

the programming starts normally, water and washing works, when it is on the programming to drain the water the pump does not turn off and shows error I30, I have already replaced the board and the same defect continues

Need a service manual & wiring diagram along with error codes .
Thanks

When cycle start water fills up and drain as intended but tub not turning.

Frigidaire model#GLFH21F8HWE

This is is a Frigidaire oven this the door lock error? Which board controls it if it is,? How can I check this issue?
I need a service manual and tech sheet and your expert advice.

Unit has no power. What do I look for and if it is the timer how do I test the timer.

I changed the infinite switch and it did the same thing.
If I begin on low it will heat and cut off but will not come back on even after 10 minutes. If I turn it off and then back on it repeats the same cycle. It will stay on high. If I set it on 3 or 4 it does the same.
Can this be the sensor in the burner?
How does it work?
It doesn’t matter if I use the single or dual settings.

All the dryer does is flash pause. It won’t even let me cancel. Therefore I can’t retrieve errors or run the service mode. The door switch tests good.
Can a bad door switch or thermal cut off or another bad part forbid me to extract the codes or even enter diagnostics?
